Viega 90640 – Frequently Asked Questions
1) What kind of connection does the Viega MegaPress 90640 make on each end?
The 90640 is a press-to-thread adapter: one end is a 3 inch MegaPress press connection and the other is a 3 inch male pipe thread (P x MPT). So it presses onto 3 inch pipe on one side and threads into a female NPT port, valve, or flange adapter on the other. No welding or thread cutting on the press side.
2) Is the Viega 90640 MegaPress fitting stainless or carbon steel?
It is 316 stainless steel, body and all. That matters if you are running stainless pipe or working in a corrosive or washdown environment, where a carbon steel MegaPress fitting would not be an appropriate match. Made in Germany.
3) Can I use the Viega 90640 to transition from pressed pipe into a threaded valve or pump connection?
That is exactly what it is for. The male pipe thread end screws into a 3 inch female NPT valve, strainer, pump port, or union, while the press end joins the 3 inch pipe run. You will still need thread sealant or PTFE tape on the threaded side, and a press tool with the correct 3 inch jaw or ring for the press side; neither is included with the fitting.
4) Does the Viega 90640 have Smart Connect, and what does that actually do for me on an inspection?
Yes, the 90640 is a Smart Connect fitting. The feature leaves an unpressed connection deliberately leaking during pressure test so an inspector or foreman can spot a joint that was missed, rather than finding it after the ceiling closes. It does not change how the joint is made, only how a missed press shows itself.
5) What part number do I order for the 3 inch stainless MegaPress press x male thread adapter?
Order Viega 90640. That is the manufacturer part number for the 3 inch x 3 inch 316 stainless MegaPress adapter with a press end and a male pipe thread end.
